About Converting Carats per Gallon to Grams per Gallon
Carat per Gallon and Gram per Gallon both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
grams per gallon = carats per gallon × 0.2
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per gallon equals 0.0528344104716 base units, and 1 gram per gallon equals 0.264172052358 base units, so dividing one by the other gives the direct carat per gallon-to-gram per gallon factor of 0.2.
Simple example
1 ct/gal × 0.2 = 0.2 g/gal
1 carat per gallon = 0.2 grams per gallon.
Real-world example
1,000 ct/gal × 0.2 = 200 g/gal
1,000 carats per gallon = 200 grams per gallon.

Frequently asked questions
How many grams per gallon are in 1 carat per gallon?
1 carat per gallon equals 0.2 grams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per gallon to gram per gallon?
Multiply the carat per gallon value by 0.2. The converter above does this instantly to whatever precision you set.
How do I convert gram per gallon back to carat per gallon?
Use the reverse factor: 1 gram per gallon equals 5 carats per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
Is the carat per gallon to gram per gallon conversion exact?
Yes. Both carat per gallon and gram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.2 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
